Houndstooth

Houndstooth, hounds tooth check or hound's tooth (and similar spellings), also known as dogstooth, dogtooth, dog's tooth, (), is a duotone textile pattern characterized by a tessellation of light and dark solid checks alternating with light-and-dark diagonally-striped checks—similar in pattern to gingham plaid but with diagonally-striped squares in place of gingham's blended-tone squares—traditionally in black and white, although other contrasting colour combinations may be used.
The oldest Bronze Age houndstooth textiles found so far are from the Hallstatt Celtic Salt... plus
